The E712 Two Bank Battery Monitor is a gauge the provides a wealth of information regarding the state of charge of your trolling and starting batteries. This gauge not only displays voltage, amperage, state of charge and time to go, but it also gives an audible alarm when the battery is getting over discharged.
Bluetooth connectivity allows you to check the battery status from an app on your phone. See realtime data and history all from up to 33′ away.
In addition to that, it records the history of the trolling battery and its charge/discharge statistics. What about the starting battery? This unit also monitors the starting battery and will give an audible alarm when it is low as well. Never find yourself with a dead starting battery again!
